There are now thirty-two confirmed persons locally with the Delta variant of Covid-19.
The majority of the cases have been detected in Trinidad.
However, Tobago has discovered its first case of Delta.
This update came from Chief Medical Officer, Dr Roshan Parasram.
The senior medical official made the revelation while addressing the Ministry of Health virtual news briefing Wednesday.
In a media release Tuesday afternoon, the Division of Health, Wellness and Family Development in the Tobago House of Assembly said the individual has no travel history and is not a known contact of any positive case.
It said the confirmation of the Delta variant was received via gene sequencing at the Faculty of Medical Sciences Laboratory, University of the West Indies.
It said unvaccinated people remain the greatest concern on the island.
The release said the greatest risk of transmission is among unvaccinated people who are much more likely to get infected, and therefore transmit the virus.
Fully vaccinated people get COVID-19 (known as breakthrough infections) less often than unvaccinated people.
Testing for variants of concern will continue and the Division said it will continue to provide updates once variants are detected in Tobago.
